Hi, here is the classification of the soil on the basis of the particle size.
Soil classification on the basis of their color, smell, porosity, place of origin, strength etc. is either not easy, or is not of much relevance to the soil engineer. Classification on the basis of the grain size and the plasticity of the soil is of much relevance to a soil engineer.
Below 0.002 mm are the Clay sizes
Between 0.002 and 0.075 mm are the Silt sizes
Between 0.075 mm and 4.75 mm are the Sand sizes
and between 4.75 mm and 80 mm are the Gravel sizes.

- Based on the grain size:
Below 0.002 mm are the Clay sizes
Between 0.002 and 0.075 mm are the Silt sizes
Between 0.075 mm and 4.75 mm are the Sand sizes
and between 4.75 mm and 80 mm are the Gravel sizes.
